3 Claims.

The invention constituting the subject matter of this application is a tool holder having a unique means for holding a socket wrench and the'like therein.

An object of the invention is to provide a tool holder simple and economical in construction, and highly efficient and durable in use, and to this end it consists in the novel combinations and means hereinafter set forth.

In manufacturing plants, the hollow headed set screw, such as the Allen is used extensively in machinery and machine elements'as means to hold the respective elements in place and together.

The manufacturer of set screws usually furnishes an L-shaped wrench to tighten and loosen the set screws. The furnished wrench at times is not suicient to properly tighten and loosen the respective screws, without the aid of another wrench or tool which in itself is a .nuisance since it interrupts the workmans work with a loss of considerable time. Further, sometimes it is not possible to use the additional wrench or tool because of lack of space.

Other objects and advantages of my invention will be pointed out in the following detailed description of my invention.

Referring to the drawing in which I have illustrated a form of my invention, which has been found to be highly satisfactory in commercial use; and wherein like numerals refer to like parts throughout, and in which:

Figure l represents a view partly in elevation and partly in section of a tool holder embodying my invention.

Figure 2 is a view in front elevation illustrating the position of the means for guiding the up and down movement of the holding element for facilitating the securement of the L-shaped wrench or the like in the tool holder.

Figure 3 is a view in elevation, illustrating the position of the holding element thereon, when it is desired to remove the wrench or tool therefrom.

Figure 4 is a sectional view on line 2--2 in Figure 2.

Figure 5 is a fragmentary View and illustrating how the wrench or the like tool may be differently mounted in the tool holder.

In the form of my invention illustrated herei'ffI provide a handle I, in the lower end portion 2 thereof, there is provided a longitudinally extending milled groove 3, at the upper end 4 of which there is provided a transverse bore 5. In the groove and bore, the L-shaped wrench 6 is removably mounted, as illustrated in the respective gures.

2 On the handle there is mounted a holding element 1, nonrotatable, but movable up and down thereon. Its down movement is limited by a stop pin 8 fast in the handle coming into contacty with the upper end 9 of the longitudinally lengthwise extending slot Il] provided in the holding element. Its up movement is limited by coming into contact with the lower end II of the aforementioned slot.

Below the aforementioned elongated slot there is provided an inverted U-shaped notch I2 ample in width to slide over the arm of the L-shaped wrench as illustrated in the respective figures of the drawing.

Adjacent the upper end of and provided in the holding element there is an annular groove I3. On the upper end portion of the holding element there is rotatably mounted a cap member I4 provided with an integral horizontally inwardly extending flange I5. This cap is held in assembled position on the holding element by means of pins I6, I6. The cap is used as a guiding and holding means when the tool holder is in use.

Placed between the cap member Ill and the xed collar` II on the tool holder is a resilient pressure applying means I8 for the purpose of holding the holding element in its down position. The resilient means is preferably in the for-m of the expansible spring type, the lower, end of which engages the upper surface of the cap I5, the upper end of which engages the under surface of the collar II.

It will be noted that the stop pin and the elongated slot in the holding element preforms the dual functions of keeping the inverted U-shaped notch properly positioned relative to the transverse bore in the tool holder, and limiting the upward movement of the sleeve to a position such that the Wrench may be installed or removed without coming into contact therewith. The pin also prevents the holding element from being separated from the handle.

In using my invention the first step in installing or removing the wrench or the like, is to pull r the holding element up, and when the pin engages the bottom end of the elongated slot, the holding element is in place to permit the installation or removal of the wrench as illustrated in Figure 3. When the wrench is properly installed the holding element is released, the expansible spring forcing it down on the handle locking the Wrench in place therein as shown in Figures 1, 2 and 5.

Finally it must be mentioned that a variety of tools may be manufactured to` be used with this tool holder such as Screwdrivers etc.

Many constructional changes may, of course. be

3 introduced in the embodiment described and illustrated by Way of example without departing from the scope of the invention.

While I have herein shown and described a preferred arrangement, it will be readily understood that changes and modifications therein may be found desirable or essential in meeting the various exlgencies of use, and I desire to be understood as reserving the right to make any and all such changes or modifications as may be found desirable or essential, in so far as the same may fall within the spirit and scope of the invention as expressed in the accompanying claims when broadly construed.

Having thus described my invention, what I claim is: A

l. A tool of the class described comprising, a handle, a shank portion connected thereto having formed in its lower end portion a longitudinally extending groove eccentric to the axis thereof and having at the upper extremity of the groove a transverse bore through the shank, a tool of L.- shaped configuration adapted to be reversibly mounted in the groove and bore, a non-rotatable slidably mounted sleeve member on the shank portion having formed therein the direction of its length an inverted U-shaped notch adapted to straddle a protruding portion of the Leshaped tool extending therethrough and an elongated slot spaced upwardly therefrom, a collar revolubly supported on the upper end portion of the sleeve member, a pin in the shank portion disposed 'within the slot and adapted to guide and limit the endwise sliding movement of the sleeve member thereon, a helical spring mounted on the shank portion, its lower end seated on the upper surface of the revolubly mounted collar, a fixed collar on the shank portion, the upper end of the helical spring engaging the under surface thereof, the revolubly mounted collar adapted to be held to guide the @010.11 @eine turned., the helical spring adapted to ensure locking the sleeve member in its down position to holdl the I p-shaped tool in the shank portion'.v

2. A device of the class described, comprising, in combination, a handle having a longitudinal groove terminating in a transverse bore for detachably receiving a tool',v a tool of L -shaped configuration having an extending lateral transanother portion of the tool mounted in the longitudinal groove, a holding elementI slidably and non-rotatably mounted on the handle and having an inverted U-shaped longitudinally extending notch therein diametrically opposite the longitudinal groove in which the laterally extending transverse portion of the L-shaped tool is engageable and being additionally adaptable to hold the I f-shaped tool in locked position in the handle.

3. A device of the class described comprising a handle having in the lower end portion thereof a longitudinally extending groove terminating in a transverse bore for detachably receiving a tool having a bent-over and laterally extending end portion, a holding element slidably and non-rotatably mounted on the handle having an inverted U-shaped notch adapted to receive the laterally extending end portion of the bent-over portion, and having distant therefrom a longitudinally extending guide slot of elongated configuration, a pin in the elongated guide slot carried by thehandle adapted to denitely guide and limit the sliding movements of the holding element on the handle, an expansible spring mounted on the handle, a collar fast on the handle remote from the upper end of the holding element, the expansible spring interposed between the upper end of the holding element and the under surface of the collar and adapted to force the holding elementv down on the handle to lock the tool in the handler in an eifectual manner.
